Answer:
Inertia
Explanation:
Inertia is best defined as the ability of an object to resist a change in position or movement. That is why when an object has a higher mass, the higher the inertia. Imagine an oncoming truck that is fully loaded versus you. The tendency for the truck to change its movement would be difficult because of its its mass. It has a lot of inertia.
Answer:
F = 50[N], to the left.
v = 10.52 [m/s]
Explanation:
<u>First problem</u>
<u />
In order to solve this problem we must apply Newton's laws, in such a way that we must perform a summation of forces on the horizontal axis. In this way we will analyze each force and the direction of action.
The offensive player is applying a force of 100N to the right, while the defensive player applies a force of 150N to the left. In this way performing the summation of forces we have.
100 - 150 = F
F = - 50 [N]
Note: The negative sign indicates that the resulting force is to the left.
<u>Second problem</u>
<u />
We must remember that the definition of speed is equal to the relationship between distance over time.
x = distance = 100 [m]
t = time = 9.5 [s]
v = x/t
v = 100/9.5
v = 10.52 [m/s]
